[0031] The embodiment of the present application provides a milling machine tool for facilitating internal processing of a large workpiece, which is used for milling a workpiece, wherein the workpiece has an inner cavity, and comprises:

[0032] abutment;

[0033] The first slide rail is arranged in the inner cavity of the workpiece and is arranged on the base along the length direction of the base.

[0035] A milling part is slidably connected to the second slide rail and is used for milling a workpiece.

[0036] The above-mentioned milling machine tooling that is convenient for internal processing of large workpieces adopts two vertical slide rails, so that the tooling can adapt to workpieces of different sizes without changing the size. Therefore, the size of the tooling is no longer a factor that limits the processing of large workpieces. The mutually perpendicular slide rails enable the milling machine tooling to perform high-precision processing on multiple planes. By controlling the movement of the slide rails, the workpiece can be processed on different planes, which improves the processing range and flexibility of the milling machine tooling and meets the needs of multi-dimensional processing.

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] See also Figure 1-Figure 6 An embodiment of the present application provides a milling machine tool 100 that is convenient for internal processing of a large workpiece 50, and is used for milling the workpiece 50. The workpiece 50 has an inner cavity 51, and includes a base 10, a first slide rail 20, a second slide rail 30, and a milling part 40.

[0039] Among them, the first slide rail 20 is arranged in the inner cavity 51 of the workpiece 50 and is arranged on the base 10 along the length direction of the base 10; the second slide rail 30 is arranged in the inner cavity 51 of the workpiece 50 and is perpendicular to the first slide rail 20 and is slidably connected to the first slide rail 20; the milling part 40 is slidably connected to the second slide rail 30 for milling the workpiece 50.

[0040] Specifically, the base 10 is the supporting structure of the entire milling machine tool, bearing the weight of the entire milling machine tool and fixed to the ground. Its function is to provide a stable basic support to ensure that the milling machine tool will not shake or deviate during the processing. The first slide rail 20 is arranged in the inner cavity 51 of the workpiece 50 and along the length direction of the base 10, and is used to provide horizontal sliding support inside the workpiece 50. It enables the milling part 40 to move horizontally inside the workpiece 50 to achieve precise processing of the inside of the workpiece 50.

[0041] Furthermore, the second slide rail 30 is disposed in the inner cavity 51 of the workpiece 50 and is perpendicular to the first slide rail 20, and is slidably connected to the first slide rail 20. Its function is to provide sliding support in a direction perpendicular to the first slide rail 20, and the sliding connection with the first slide rail 20 enables the milling part 40 to perform complex movements inside the workpiece 50. This design can realize the processing of multiple planes inside the workpiece 50. The milling part 40 is slidably connected to the second slide rail 30 and is used to perform milling operations inside the workpiece 50. It may include a tool, a tool holder, etc., which is used to cut the workpiece 50 to achieve the desired shape and size. The movement of the milling part 40 is linked with the second slide rail 30 to realize high-precision milling operations inside the workpiece 50.

[0042] In summary, the above-mentioned milling machine tool adopts two vertical slide rail designs, so that the tool can adapt to workpieces 50 of different sizes without changing the size. The size of the tool is no longer a factor that limits the processing of large workpieces 50. The mutually perpendicular slide rails enable the milling machine tool to perform high-precision processing on multiple planes. By controlling the movement of the slide rails, the workpiece 50 can be processed on different planes, which improves the processing range and flexibility of the milling machine tool and meets the needs of multi-dimensional processing.

[0043] In a specific implementation example, the first slide rail 20 further includes a first fixing plate 21 , which is disposed between the first slide rail 20 and the second slide rail 30 and fixedly connected to the bottom of the second slide rail 30 .

[0044] Specifically, the first fixed plate 21 is located between the first slide rail 20 and the second slide rail 30, and is fixedly connected to the bottom of the second slide rail 30. Its function is to enhance the stability and rigidity of the first slide rail 20, and ensure that no sliding deviation or swing occurs during the processing. During the processing, even if the tooling is subjected to a certain processing force or vibration, the presence of the fixed plate can effectively absorb and disperse these forces, reduce the impact on the movement of the slide rail, and ensure the accuracy and stability of the processing process.

[0045] In a specific implementation example, the second slide rail 30 further includes a second fixing plate 31 , which is disposed between the second slide rail 30 and the milling member 40 and fixedly connected to the bottom of the milling member 40 .

[0046] Specifically, the second fixing plate 31 is located between the second slide rail 30 and the milling part 40, and is fixedly connected to the bottom of the milling part 40. Its function is to increase the stability between the second slide rail 30 and the milling part 40, and ensure that no deviation or swing occurs during the processing. By setting the fixing plate, the accuracy and stability of the processing process can be improved, and the quality of the processing result can be guaranteed.

[0047] Furthermore, during the machining process, the workpiece 50 is clamped in the fixture, and by controlling the movement of the first slide rail 20 and the second slide rail 30, the milling part 40 can perform precise machining in the horizontal and vertical directions inside the workpiece 50. The second fixing plate 31 is fixedly connected to the bottom of the milling part 40, ensuring the stability and precision of the milling part 40 during the machining process. In this way, the milling machine fixture can achieve high-precision machining of multiple planes inside the workpiece 50, meeting the machining requirements for the complex structure inside the workpiece 50.

[0048] In a specific implementation example, the second fixed plate 31 includes a first layer 311 and a second layer 312, the first layer 311 is fixed on the second slide rail 30, the second layer 312 is fixed on the milling part 40, and the second layer 312 can be flipped around one end of the first layer 311 along the length direction of the second fixed plate 31.

[0049] Specifically, the second fixing plate 31 is used to fix the milling part 40 and provide stable support. It includes a two-layer structure, the first layer 311 is fixed on the second slide rail 30, and the second layer 312 is fixed on the milling part 40, and has the characteristic of being able to flip around one end of the first layer 311 along the length direction. The first layer 311 is fixed on the second slide rail 30, and is used to provide basic support and fixation for the second fixing plate 31. It ensures a firm connection between the second fixing plate 31 and the second slide rail 30. The second layer 312 is fixed on the milling part 40, and its function is to enable the milling part 40 to rotate in a specific direction during the processing, thereby realizing the processing of different parts inside the workpiece 50.

[0050] Furthermore, during the processing, the milling part 40 is fixed on the second layer 312, and a stable support structure is formed between the entire fixed plate and the second slide rail 30 through the fixed connection between the first layer 311 and the second slide rail 30. At the same time, the second layer 312 has a flipping feature and can be flipped along the length direction around one end of the first layer 311. By adjusting the flipping angle of the second layer 312, the processing direction and angle of the milling part 40 can be changed, and accurate processing of different positions inside the workpiece 50 can be achieved.

[0051] In summary, the design of the above-mentioned milling machine tooling includes components such as a base 10, a first slide rail 20, a second slide rail 30, a milling part 40, and related fixed plates and rotating components 60. The combined design of these components realizes high-precision processing inside a large workpiece 50. The base 10 provides stable support for the entire system, the first slide rail 20 and the second slide rail 30 provide sliding support in the horizontal and vertical directions, and the milling part 40 is used for actual processing operations. The setting of the fixed plate increases the stability between the slide rail and the milling part 40, ensuring the accuracy and stability during the processing. In particular, the design of the second fixed plate 31 allows the milling part 40 to rotate in a specific direction during the processing, thereby improving the flexibility and efficiency of the processing. Through these designs, the milling machine tooling can realize high-precision processing of multiple planes and multiple angles inside the workpiece 50, meeting the processing requirements of complex workpieces 50.

[0052] In a specific implementation example, the milling machine tool further includes a rotating assembly 60 , one end of which is disposed on the first slide rail 20 , and the other end of which passes through the base 10 and contacts the ground, so as to drive the first slide rail 20 to rotate.

[0053] Specifically, the rotating assembly 60 is one of the key components of the milling machine tool, and its function is to provide rotational power to drive the first slide rail 20 to rotate. Its design enables the milling machine tool to realize rotational processing inside the workpiece 50, increasing the flexibility and diversity of processing. One end of the rotating assembly 60 is fixed to the first slide rail 20. Through this connection, the rotating assembly 60 can directly act on the first slide rail 20 to achieve control of its rotation. This ensures that the rotational power can be effectively transmitted to the first slide rail 20, thereby realizing the need for rotational processing.

[0054] Furthermore, the other end of the rotating assembly 60 passes through the base 10 and contacts the ground. This design provides a stable support and rotation axis, ensuring stability and reliability during the rotation process. At the same time, through contact with the ground, the rotating assembly 60 can obtain the required rotational power to achieve rotational drive of the first slide rail 20.

[0055] In a specific implementation example, the rotating assembly 60 includes a rotating rod 61, a motor 62 and a connecting platform 63. The connecting platform 63 is arranged on the base 10 and is fixedly connected to the first slide rail 20. The rotating rod 61 is arranged on the connecting platform 63 and is fixedly connected to the connecting platform 63. The motor 62 is arranged on the rotating rod to drive the rotating rod 61 to rotate.

[0056] Specifically, the rotating rod 61 is one of the main components of the rotating assembly 60, and its function is to provide rotation support and transmit rotational power. The rotating rod 61 is fixed on the connecting platform 63, and can withstand the rotational force transmitted by the motor 62, so that the entire assembly can achieve rotational motion. The motor 62 is the power source of the rotating assembly 60, and its function is to provide rotational power and drive the rotating rod 61 to achieve rotational motion. Driven by the motor 62, the rotating assembly 60 can quickly and accurately perform rotational processing operations, thereby improving processing efficiency and accuracy.

[0057] Furthermore, the connecting platform 63 is a component that fixes the rotating assembly 60 on the base 10, and its function is to provide stable support and fixed connection. The connecting platform 63 is fixedly connected to the base 10 and fixedly connected to the first slide rail 20, ensuring the stability and reliability of the rotating assembly 60, while allowing the rotating motion to be accurately transmitted to the first slide rail 20.

[0058] In a specific implementation example, the milling machine tool further includes a lifting component 70, which abuts against an end of the rotating rod away from the rotating table and is used to control the movement of the rotating rod in the vertical direction.

[0059] Specifically, the lifting member 70 is an important component of the milling machine tooling, and its function is to control the movement of the rotating rod in the vertical direction. The design of the lifting member 70 can control the height of the rotating rod by adjusting its position, thereby adjusting the position of the milling part 40 and realizing the processing of different depths inside the workpiece 50. The lifting component supports and controls the rotating rod by resisting the end of the rotating rod away from the rotating table. When the lifting component contacts the rotating rod, the movement of the rotating rod in the vertical direction can be limited, thereby controlling the processing depth and position of the milling part 40.

[0060] Furthermore, during the processing, the position of the lifting member 70 is adjusted so that the lifting assembly contacts the rotating rod, thereby limiting the vertical movement of the rotating rod. In this way, the position of the milling member 40 can be controlled to achieve processing of different depths inside the workpiece 50. When the processing depth needs to be changed, the height of the rotating rod can be adjusted by adjusting the position of the lifting member 70, thereby achieving the adjustment of the processing depth.

[0061] In a specific implementation example, the milling machine tooling also includes a fixing assembly 80, which includes a connecting rod 81 and a column 82. One end of the column 82 is arranged on the base 10, and the other end is fixedly connected to the connecting rod 81. The connecting rod 81 is fixedly connected to the lifting member 70 at one end away from the column 82 to prevent the lifting member 70 from deviating.

[0062] Specifically, the fixing assembly 80 is a key part of the milling machine tooling, and its function is to provide stable support and fixed connection. It is composed of a connecting rod 81 and a column 82, and is used to fix the lifting member 70 and maintain its correct position. The connecting rod 81 is used to connect the column 82 and the lifting member 70, and at the same time plays a supporting and fixing role. The design of the connecting rod 81 enables the lifting member 70 to be fixed in the correct position to prevent it from deviating or shaking. The column 82 is the supporting part of the fixing assembly 80, one end of which is arranged on the base 10, and the other end is fixedly connected to the connecting rod 81. The column 82 provides a stable supporting structure to ensure the stability and reliability of the fixing assembly 80.

[0063] Furthermore, the fixing assembly 80 is fixedly connected to the base 10 through the connecting rod 81, and is fixedly connected to the lifting member 70 to maintain the correct position of the lifting member 70. The column 82 provides a stable support structure to prevent the lifting member 70 from deviating or shaking. In this way, the stability of the lifting member 70 during the processing can be ensured, and the processing accuracy and quality can be guaranteed.

[0064] In a specific implementation example, the fixing components 80 are symmetrically arranged on both sides of the base 10 along the width direction of the base 10 .

[0065] Specifically, the fixing components 80 are located on both sides of the base 10 and are symmetrically distributed. This symmetrical layout helps to balance the structure of the milling machine tool and improve the overall stability and balance. By symmetrically setting up the fixing components 80 on both sides of the base 10 along the width direction, the weight of the milling machine tool can be evenly distributed, providing stable support and preventing tilting or instability during processing. The balanced structure helps to reduce vibration and deformation caused by imbalance, thereby improving the accuracy and quality of processing.

[0066] Furthermore, when the milling machine tool is used for processing, the fixed components 80 are symmetrically set up on both sides along the width direction of the base 10, so that the tool remains balanced during the processing. When the rotating component 60 drives the milling part 40 for processing, the balanced support of the fixed component 80 ensures the stability of the tool, thereby ensuring the accuracy and efficiency of the processing process.

[0067] In summary, sliding support is provided in the horizontal and vertical directions, so that the processing tool can be accurately moved and positioned inside the workpiece 50. The processing tool is allowed to perform complex multi-axis movements inside the workpiece 50, achieving more flexible and precise processing operations. The rotating rod provides rotational power, so that the processing tool can perform rotational processing inside the workpiece 50. Combined with the movement of the slide rail, it is possible to achieve rotational processing while moving in multiple planes, increasing the diversity and flexibility of processing. The lifting member 70 controls the movement of the processing tool in the vertical direction, and can adjust the processing depth and position. Combined with the movement of the rotating rod and the slide rail, processing of different depths and angles inside the workpiece 50 can be achieved, increasing the accuracy and diversity of processing, and the fixed component 80 provides stable support and fixed connection to ensure the overall stability and balance of the processing system. The fixed connection between the connecting rod 81 and the column 82 ensures the stability and balance of the milling machine tooling, preventing instability or deviation during processing.

[0068] The coordination of the above-mentioned multiple components comprehensively utilizes the movement of the slide rail, the rotation of the rotating rod and the control of the lifting member 70, which can realize complex multi-axis processing inside the workpiece 50 and meet the requirements for high-precision processing of the workpiece 50. Combining the functions of rotation and movement, it is possible to achieve all-round processing of the complex structure inside the workpiece 50, improving the processing efficiency and quality. Through the stable support of the fixed component 80, the overall stability and reliability of the processing system are ensured, the vibration and deformation during the processing are reduced, and the processing accuracy is further improved. Combining the fixed component 80 with other processing components can form a fully functional, stable and reliable processing system, which is suitable for high-precision processing of complex structures inside large workpieces 50.

[0069] In a specific implementation example, a plurality of fixing holes 11 are provided on the base 10 for fixing the workpiece 50 to prevent the workpiece 50 from moving.

[0070] Specifically, the fixing hole 11 provides a means for fixing the position and direction of the workpiece 50, preventing the workpiece 50 from moving or deflecting during the processing. The fixing hole 11 allows the workpiece 50 to be firmly fixed on the base 10 using various clamps or clamp elements, ensuring the stability and safety of the workpiece 50 during the processing. By fixing the workpiece 50, it can be ensured that the workpiece 50 will not move or deflect during the processing, thereby maintaining the accuracy and stability of the processing. And avoid safety accidents caused by the accidental movement of the workpiece 50 during the processing.

[0071] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
